 Machine-to-Machine (M2M) applications will be developed in various sectors of the industry at a rapid pace over the next five years, reaching an inflexion point by 2020 as the Internet of Things (IoT) begins a high growth phase. With increasingly more devices connected to the Internet in which critical business processes depend, the threats to applications increase in terms of incidence, severity, and impact. 
   
 It is important to recognize that applications are susceptible to physical attacks on devices as well as network-level attacks, which in many cases have different issues and solutions.  
 The M2M industry is quickly recognizing the need to deal with security and privacy issues pertaining to M2M, but understanding the specific issues and solutions are not broadly...
